Embodiment 1

[0021] Example 1, a port construction reclamation material using silt, which is made by mixing tailings sand, silt and cement, the water content of the silt is 60%, and the weight ratio of silt, tailings sand and cement is 1:3 : 0.04. It is prepared by conventional methods of mixing.

Embodiment 2

[0022] Embodiment 2, a port construction reclamation material using silt, it is made by mixing tailings sand, silt and cement, the water content of the silt is 100%, and the weight ratio of silt, tailings sand and cement is 1: 5 : 0.06.

[0023] Its preparation method steps are as follows:

[0024] (1) Grab and store the dredged fill sludge with a water content of 100%;

[0025] (2) Add tailings sand and cement to the sludge according to the weight ratio, and stir evenly to obtain a mixture;

[0026] (3) Use a high-pressure delivery pump to fill the mixture into the mold bag.

Embodiment 3

[0027] Example 3, a port construction reclamation material using silt, which is made by mixing tailings sand, silt and cement, the water content of the silt is 80%, and the weight ratio of silt, tailings sand and cement is 1:4 : 0.05.

[0028] Its preparation method steps are as follows:

[0029] (1) Grab and stockpile dredged fill sludge until its water content is 80%;

[0030] (2) Add tailings sand and cement to the sludge according to the weight ratio, and stir evenly to obtain a mixture;

[0031] (3) Use a high-pressure delivery pump to fill the mixture into the filling material.

Abstract

The invention relates to a harbor construction sea reclaimed material utilizing silt, which is prepared by mixing gangue sand, the silt and cement. Water content of the silt is 60%-100%, and the weight ratio of the silt, the gangue sand and the cement is 1: 3-5: 0.04-0.06. A preparation method of the harbor construction sea reclaimed material utilizing silt is further disclosed. The material and the method achieve waste object utilization of the gangue sand and the silt. The material is high in strength, low in construction cost and capable of achieving quick solidification of silt and saving a large amount of natural resources. The material can be applied to projects such as sand quilt blowing filling, filtering guide layers, sand cushion layers and land area backfilling.

Description

technical field [0001] The invention relates to a new type of building material for port engineering, in particular to a port construction reclamation material utilizing silt; the invention also relates to a preparation method of the above reclamation material. Background technique [0002] Port engineering construction requires a large amount of sand and gravel resources. Along with environmental protection, sand and gravel resources are becoming increasingly tense, which seriously restricts the speed and quality of port construction. Port construction requires the dredging of a large amount of silt. In the past, the silt was dumped out to sea, causing waste and pollution. Due to the fine silt particles, high water content, and poor physical and mechanical indicators, the silt must be treated during port construction, and the silt must be excavated and land reclamation, which is used as a foundation after drainage and consolidation. Vacuum preloading and surcharge preload...
